I thoroughly enjoyed my stay at Ollis' place. The location is great; right in the centre of Bangkok. There is a 24 hour grocery shop just outside and it is only a 5-10 minute walk to the BTS (skytrain) station which allows easy travel all around the city. The condo itself is very good value for money and provides a pool and small gym facility as well as laundry facilities for a small fee.
Olli is a great host who communicates well with guests.
I highly recommend staying here!
